It is stated in the passage that English is a second language used by all nations
has enabled England to spread its influence beyond its borders
is spoken by the majority of people in the world
is the only language used in specialized higher education
is not exclusively spoken at the United Nations
According to the passage, English as a second language has increased its influence around the world due to its use in aviation
has strengthened its grip on international diplomacy
does not take the place of the mother tongue either culturally or emotionally
is most important in the world of commerce
is more important than a person's first language
We can infer from the passage that English will soon be spoken by everyone in the world
many educational books and textbooks are written in English
England's political influence is constantly increasing
there would be no international diplomacy without English
people around the world would not have such similar interests without English
131 HEALTH EDUCATION IN SCHOOLS Human biology is a detailed and complicated study. Thus, for the purposes of health education in schools, it is best approached from the point of view of function rather than structure. The detailed anatomy and physiology of the heart and circulation, for instance, are not needed, but students should know that the heart's function improves with use and that regular exercise is the best way to avoid distress upon exertion. Thus, the basic knowledge required to live a healthy life is that oxygen is supplied to the muscles by a partnership of lungs and heart, the lungs taking in a supply and the heart distributing it. Exercise involves a call for more oxygen and, if the heart is not trained to deliver a full volume of blood with each beat, the lungs must work harder to compensate. These simple facts can be appreciated without the need for elaborate detail.
